Application filed March 11, 1921, Serial No. 451,435. Renewed June26,1922. Serial No. 570,933.

To all whom it may concern:

Be it known that I, JosnPH S. Pownn, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Washing Machines, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

My invention relates to washing machines and in particular to washingmachines having a moving tub of the domestic power type.

The object of my invention is to reduce the consumption of currentnecessary for the reciprocation of a washing machlne tub. It is afurther object of my invention to provide a means of saving thisconsumption of current which may be detachable for shipping, so that ifnecessary it may go under a separate freight classification and reducethe expense of shipments of washing machines. It is a further object ofmy inventlon to provide a durable, simple and easily accessble devicefor the saving of the power necessary to reciprocate the washing machinetub.

Referring to the drawings:

Fig. 1, is a side elevation of a complete washing machine showing thepower savlng device installed;

Fig. 2, is a side elevation of a tub with my power saving deviceinstalled; and,

Fig. 3, is an end elevation of 'the bottom of the tub with the deviceinstalled.

Referring to the drawings, 1 is a frame of the machine casing in whichis mounted a tub 2 that reciprocates about the center 3 and is actuatedin its reciprocation by the flexible connecting rod 4 which is connectedat 5 to a suitable crank 6 mountedon a cross shaft 7 that is driventhrough the gears 8 and 9 from the shaft 10. This shaft 10 is driven byan electric motor 11.

A flexible connecting rod connects the source of power from the crank 6to the tub This is effected by the connecting rod parts 4 and 5 whichare joined together by the rods 18 passing from the part 4 through eyesin the part 5. Helical springs 19 are embraced between the parts 4.- and5 and adapted to be compressed between those parts. The springs 19 areguided and mounted upon the rod 18. The springs 20 are mounted upon therod 18 adjacent the part 5. They are retained on these rods by the nuts21. This connecting rod serves to pick up the torsional, longitudinaland lateral strains, any inequality in delivering the power from thecrank 6 to the tub 2, and also serves to take up the shock at the end ofeach stroke which may be caused by converting the direction of movementof the tub and the weight 15 from one direction to another. Any shockthat might be imparted to the driving mechanism by reason of a suddenchange in direction is suitably absorbed by this flexible connectingrod.

Mounted upon the sides of the tub are suspension members 1212 that arejoined at 13 on a rod 1 1. A U-shaped weight 15 cut away at 16 is placedover such rod so that it is adapted to swing about this rod 14. Similarsuspension members are placed at either side of the tub.

When the electric motor starts to reciprocate through its mechanism inthe tub, it is found that, due to the pendulum weight 15, the initialinertia having been once overcome, the tub is reciprocated back andforth with great ease so that nearly one half of the ordinary currentconsumption is saved. It takes a very considerable amount of electriccurrent to furnish power for moving the weight of the tub and water,together with the clothes in the tub back and forth so that the clotheswill be dragged over the stepped bottom of the tub and the water movedthrough the clothes to wash them. This weight also gives a steadypowerful. movement to the tub which cannot be secured by other means.The momentum of the weight carries the tub through each stroke with theminimum of strain and stress upon the parts of the mechanism due to itssteady, rythmic. action.

lVhile I have shown and described certain features as constituting myinvention, it will be understood that parts have been shown for purposesof illustration only, and that I do not desire to be limited to suchdetails, as obvious modifications will occur to a person skilled in theart.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. In a washing machine, the combination, a frame, a tub, means ofpivoting said tub on said frame, means of reciprocating said tub, a pairof diagonally disposed rods on either side of said tub joined at theirlower end, a connecting rod extending between the joined ends of saidrods on eithervside and a detachable U-shaped weight mounted over saidconnecting rod and adapted to loosely swing thereon in the arc of acircle.
